A Correct answer
Explanation

Correct. The method of separating the grain from the stalk is called threshing. It is basically the beating of dry stalks to shake off the dried grains. Even though the large stalks can be separated from the grains by threshing, the grains still have dried husk and chaff, which have to be separated and thrown away before the wheat can be used. This method is called winnowing. The husk is blown away as it is much lighter than the grain. So, when the grains are gently dropped to the ground, only the wheat grains collect there, while the husk blows away.
